Cov ncauj lus ntsuas
1. 3 P Circuit Courmer
Ua Haujlwm:Nws muaj peb sab hauv sab hauv kev sib cuag uas ib txhij txuas thiab txiav tawm peb theem baspors. Nws tsis tswj tswj hwm nruab nrab (n).
Kev Ua Haujlwm Lub hauv paus:When a fault such as a short circuit or overload occurs, the circuit breaker trips, disconnecting the three phase conductors and de-energizing the load. Txawm li cas los xij, cov neeg coj ua nruab nrab ntawm cov neeg coj ua ke tseem txuas nrog.
Daim Ntawv Thov Qhia:
Ntshiab peb {-} pase balanced loads:Cov ntawv thov puas yog suav nrog peb {{- page motors thiab peb {{}}}}}}}}}}}}} {pawv fais Furnaces. Cov cuab yeej siv no tsis tas yuav muaj kev tswj hwm nruab nrab, lossis thaum peb ntu yog sib npaug, lub nruab nrab tam sim no yog xoom.
Nqi thiab Chaw:Piv rau 4P Circuit Coilcuit Charcuit Courers, 3p Circuit Court cov neeg txhaum tsis tshua kim thiab nqa cov chaw tsawg hauv lub thawv faib khoom.
2. 4 P Circuit Courmer
Ua Haujlwm:Nws muaj plaub qhov kev sib tshuam sib txuas uas tuaj yeem sib txuas ib txhij txuas los yog txiav tawm peb theem ua tus coj thiab ib qho kev coj noj coj ua.
Kev Ua Haujlwm Lub hauv paus:Thaum tripped, nws disconnects txhua tus neeg coj cwj pwm (peb theem pib thiab ib qho kev coj ua), cais cov thauj khoom ntawm lub zog.
Daim Ntawv Thov Zaj Dab Neeg (Vim li cas txiav tawm cov kab nruab nrab?):
Tshuaj Tiv Thaiv Kev Nyab Xeeb:Thaum siv raws li lub zog loj hloov, txhua tus neeg nyob yuav tsum raug txiav tawm kom ntseeg tau tias kev nyab xeeb ntawm kev nyab xeeb ntawm cov neeg kho mob. Nyob rau hauv ib qho unbalanced peb {{-}}}}} yuav muaj nyob rau ntawm kab nruab nrab (tsis muaj nyob ntawm xoom muaj peev xwm). Yog tias tsuas yog cov theem theem tau raug txiav tawm, tseem muaj kev pheej hmoo ntawm hluav taws xob thaum kov txoj kab nruab nrab.
Muaj ib qho ntawm ib qho -} theem theem thauj khoom:Nyob rau hauv ib lub tuam tsev fais fab (380v / 220V tshuab), muaj ob qho tib si {{{{{}} paim teeb thiab cov teeb meem). Cov tib {-} paim li dratating tshuab ntawm nruab nrab thiab nruab nrab kab, ua rau lub qhov tsis txaus ntseeg. Nyob rau hauv cov xwm txheej no, tus lej 2P Circuit Court yog tsim nyog los xyuas kom meej qhov nruab nrab kab tuaj yeem raug txiav ua kom nyab xeeb.
Tiv thaiv nruab nrab kab overloads:Hauv cov tshuab faib hluav taws xob niaj hnub no, cov thib peb ua kom sib raug zoo tsim los ntawm ntau cov kab uas tsis muaj kev sib txawv thiab ua kom muaj kev tsis sib xws, txawm tias theem ntawm theem tam sim no. Tus 4P Circuit Court breaker muab kev tiv thaiv ntau dua cov khoom.
Cov Cai Tswj:Raws li cov khoom siv hluav taws xob teeb tsa (xws li Tuam Tshoj GB tus qauv thiab cov qauv hauv TT
